DS259 Double Hung Window Restrictor

The latest addition to Doric’s expansive range of window restricting safety devices, the DS259 is specifically designed for use with residential double hung windows. The innovative device streamlines the window restriction mechanism, restricting the opening range of the top and bottom sashes simultaneously. The distance to which the sashes can be opened is pre-determined at the time of installation.

The easy to install DS259 does not interfere with existing window balance mechanisms and features a key operated removable body that can be easily removed for cleaning or emergency egress. The double hung window restrictor can be keyed alike to suit other Doric locking devices, and is available either a complete kit to suit one window or a bulk trade pack of 20 restrictor bars compatible with the DS255.
